4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter adrian.hunter@intel.com
commit 692d0e63324d2954a0c63a812a8588e97023a295 upstream.
Branch stacks do not necessarily have the same cpumode as the 'ip'. Use the fallback functions in those cases.
This patch depends on patch "perf tools: Add fallback functions for cases where cpumode is insufficient".
